Use of Computer Simulation to Reduce the Energy Consumption in a Tall Office Building in Dubai-UAE- ICEBO 2009
Buildings are a major consumer of energy and thus have a significant impact on the environment. The use of artificial lights is a major contributor to the energy usage in a typical office building using electricity to run the lights and also increasing the cooling load due to its heat dissipation. Proper design for the maximization of natural light helps reduce the use of artificial lights and results in reduction in the buildings energy consumption. Computer simulation of the lighting and energy consumption in a typical tall office building in Dubai-UAE is used to optimize the effectiveness of natural lighting penetration and calculate the associated energy savings. Two alternative building designs are proposed and tested. The overall energy savings for the whole building reached 31.4 % for the proposed oval shaped design. This represents a significant reduction in the buildings electricity load and thus its impact on the environment.

The Use of Useful Daylight Illuminance (UDI) to Test New Designs for Improving Daylight Performance of Office Buildings in Dubai-UAE. BUiD 2009
UDI provides a convenient method of assessing daylight and solar penetration by using dynamic climate-based conditions that change across various locations and orientations. The aims of this study is to demonstrate how the UDI metric can be constructed from the huge excel measurements in order to be used as fast evaluating metric for different design solutions. The UDI scheme is both richly informative and extremely simple. It would give a designer of a space quick indication of likely tendency for discomfort, potential high or low levels of illumination and solar gains for a space given its specific characteristics. In addition, UDI gives an idea about daylight distribution and space uniformity.
Direct And Diffuse Illuminance Falling On Vertical External Facades.
BUiD 2010
The first step towards designing building that achieves daylight performance internally is to obtain information on the amount of daylight available externally. A Cumulative frequency distributions of daylight availability was reported from Shikh Zayed offices towers in different locations and orientations. 3D Max Design simulations was used in this research as an approach to obtain daylight levels on vertical surfaces. Measurements of direct and diffuse outdoor illuminance falling on vertical facade plane at three orientations (N, W and S)was collected by a vertical light meter placed on each facade on three Different Towers (Al Musa Tower, Index Tower and the Golden tower).
